Research on Optimization of Flow Field and Combustion Performance in Boilers With Combined Near‐Wall Air Supply Systems

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the pulverized coal boiler industry, reducing NOx emissions has become a critical objective. Although low‐NOx combustion technologies are effective, they may lead to localized high‐temperature corrosion. To address this issue, near‐wall air supply technology has been introduced, which involves injecting an appropriate amount of air near the
